The answer is : 4140. set it up the problem. do 2 times 5 then 2 times 4. also carry the one up top and add it. then multiply 2 and 3. you should get 690. to the line underneath you add 0 under the last digit. then you multiply 1 times 5, 1 times 4 and 1 times 3. for that second line you should get 3450. add 690 and 3450 and you should get 4140. i hope this helped

Step-by-step explanation:
The general form of the quadratic equation is :
The given equation is x²+4x+20=0
On comparing the given equation and the general equation, we find that
a = 1, b = 4 and c = 20
Hence, the correct option is a=1 b =4 c = 20.
If the equation is 2x²+6x+5=0, then
a = 2, b = 6 and c = 5
If the equation is -2x²+x+5
a = -2, b = 1 and c = 5
